Reservoir tank for brake system
In accordance with one aspect of the present disclosure, a reservoir tank for a brake system can be provided, and the reservoir tank includes an upper body provided with an oil injector through which oil is injected, a lower body provided with a port through which oil is supplied to a master cylinder and coupled to the upper body to form an oil space, and a partition provided in the oil space to prevent the oil from being gathered at one side, wherein the partition includes a plurality of first partitions formed vertically and a second partition provided between the plurality of first partitions and provided with a communication space formed therein to communicate with the port.
1 . A reservoir tank for a brake system, comprising:
an upper body provided with an oil injector through which oil is injected;
a lower body provided with a port through which oil is supplied to a master cylinder and coupled to the upper body to form an oil space; and
a partition provided in the oil space to prevent the oil from being gathered at one side,
wherein the partition includes a plurality of first partitions formed vertically, and a second partition provided in a space formed between opposing faces of at least two of the plurality of first partitions and provided with a communication space formed therein to communicate with the port, and
wherein the second partition has a hollow side wall surrounding an inner hole of the port and protruding from an inner bottom of the lower body and an opening, and an uppermost end of the hollow side wall of the second partition is spaced apart from an inner top of the upper body,
wherein the hollow side wall is spaced apart from an inner side wall of the lower body which forms the outline of the oil space and is not connected to the inner side wall of the lower body except through a bottom surface of the oil space.
2 . The reservoir tank of claim 1 , wherein the opening is formed in a wall surface of the second partition.
3 . The reservoir tank of claim 1 , wherein the opening is formed to extend vertically.
4 . The reservoir tank of claim 1 , wherein the second partition is formed on the upper body to be inclined at a predetermined angle with respect to the port.
5 . The reservoir tank of claim 1 , wherein the partition is integrally formed with at least one of the upper body and the lower body.
6 . The reservoir tank of claim 1 , further comprising:
a float configured to vertically move along an oil level in the oil space to measure an amount of residual oil in the oil space; and
a float guide configured to guide the vertical movement of the float.
7 . The reservoir tank of claim 6 , further comprising an oil detector provided on a lower end portion of the float.
8 . The reservoir tank of claim 1 , wherein the second partition is provided in a hollow cylindrical shape.
9 . The reservoir tank of claim 1 , wherein the port is provided as a plurality of ports.
10 . The reservoir tank of claim 1 , wherein the upper body further includes a reservoir cap detachably provided on the oil injector.
11 . The reservoir tank of claim 7 , comprising:
a detection sensor configured to detect whether a distance between the float and the oil detector is a predetermined distance or less; and
a warning light turned on upon receiving a signal from the detection sensor.
12 . The reservoir tank of claim 1 , wherein the opening of the second partition is formed in the hollow side wall of the second partition at a side opposite to a side at which the second partition faces the oil injection portion.
13 . The reservoir tank of claim 1 , wherein the hollow side wall of the second partition is continuously formed from one end of the opening of the second partition to another end of the opening of the second partition.
14 . A reservoir tank for a brake system, comprising:
an upper body provided with an oil injector through which oil is injected;
a lower body provided with a port through which oil is supplied to a master cylinder and coupled to the upper body to form an oil space; and
a partition provided in the oil space to prevent the oil from being gathered at one side,
wherein the partition includes a plurality of first partitions formed vertically, and a second partition provided in a space formed between opposing faces of at least two of the plurality of first partitions and provided with a communication space formed therein to communicate with the port, and
wherein the second partition has a hollow side wall surrounding an inner hole of the port and an opening located directly behind the inner hole of the port,
wherein the hollow side wall is spaced apart from an inner side wall of the lower body which forms the outline of the oil space and is not connected to the inner side wall of the lower body except through the bottom surface of the oil space.
15 . The reservoir tank of claim 14 , wherein the hollow side wall of the second partition is continuously formed from one end of the opening of the second partition to another end of the opening of the second partition.
