A suspension includes: wheel supporting members for supporting wheels, a leaf spring having both end portions each arranged on an upper side of the respective wheel supporting member; a pivot supporting the leaf spring, and receiving pieces interposed between the wheel supporting members and the both end portions of the leaf spring respectively. Each of the wheel supporting members includes a recess portion on which one of the receiving pieces is mounted. Each of the receiving pieces includes an engaging portion for engaging with one of the both end portions of the leaf spring. Each of the receiving pieces includes an elastic member and a first metal plate joined on the elastic member. The elastic member can deform to follow a displacement of a relative position between the leaf spring and one of the wheel supporting members.
1. A suspension comprising:
wheel supporting members for supporting left and right wheels respectively on a vehicle body movably in a vertical direction;
a leaf spring disposed on a lower side of the vehicle body, the leaf spring extending in a vehicle width direction and having both end portions each arranged on an upper side of the respective wheel supporting member;
a pivot projecting from a lower face of the vehicle body and supporting on the vehicle body a middle portion of the leaf spring in the vehicle width direction; and
receiving pieces interposed between the wheel supporting members and the both end portions of the leaf spring respectively;
wherein each of the wheel supporting members includes a recess portion opened upwardly on which one of the receiving pieces is mounted to be prevented from detaching;
each of the receiving pieces includes an engaging portion for engaging with one of the both end portions of the leaf spring to prevent detachment of the leaf spring; and
each of the receiving pieces includes an elastic member and a first metal plate joined on an upper face of the elastic member, the elastic member capable of deforming to follow a displacement of a relative position in the vehicle width direction between the leaf spring and one of the wheel supporting members.
2. The suspension according to claim 1 , wherein each of the receiving pieces includes a second metal plate joined on a lower face of the elastic member.
3. The suspension according to claim 1 , wherein the engaging portion is an erected wall disposed along one of the both end portions.
4. The suspension according to claim 3 , wherein the first metal plate has both end portions in a front and rear direction of the vehicle, the both end portions bent upwardly to form a portion of the erected wall.
5. The suspension according to claim 1 ,
wherein
the leaf spring comprises two sheets of leaf springs laminated to each other and sliders;
the sliders are interposed respectively between the two sheet of the leaf springs at both end portions thereof; and
the engaging portions of the receiving pieces are hole portions into which the both end portions of the two sheets of the leaf springs can be inserted along with the sliders.
6. The suspension according to claim 5 , wherein the first metal plate has both end portions in a front and rear direction of the vehicle, the both end portions bent upwardly to form a portion of the erected wall.
