Abstract

PROBLEM TO BE SOLVED: To provide a vehicle in which a trunnion suspension is installed straddling over a driving shaft and a driven shaft, whereby the grounding load of each driving wheel is enlarged certainly using a low-cost and lightweight construction. SOLUTION: When a vehicle is empty, a leaf spring 5 of a trunnion suspension 15 is in contact with the oversurface of a driving shaft axle housing 8, while the tail of the leaf spring 5 is detained with the bend 21 of a bracket 20 fixed to a side frame 1, wherein a minor gap 23 is reserved between the oversurface of driven shaft axle housing 10 and the leaf spring 5. When the car is loaded, the vehicle height is sunk by deflection of the leaf spring 5, which contacts with the oversurface of the driven shaft axle housing 10.

との間に少しの空隙２３が生じている。In this case, as shown in FIGS. 1 and 2, a bracket 20 having a substantially L-shaped cross section is fixed to the side surface of the side frame 1 by bolts 21.
The lower surface of the rear end of the leaf spring 5 is supported on the distal end bent portion 22 of the drive shaft, so that the lower surface of the front end of the leaf spring 5 is connected to the drive shaft axle housing 8 or the spring seat fixed to the upper surface of the drive shaft axle housing 8. On the other hand, a small gap 23 is formed between the driven shaft axle housing 10 or the spring seat fixed to the upper surface of the driven shaft axle housing 10 on the lower surface of the rear end of the leaf spring 5 while being in contact.

る。Therefore, the sprung load applied to the leaf spring 5 is, as in the case of a normal trunnion suspension, the distance A from the contact point between the leaf spring 5 and the drive shaft axle housing 8 to the spring shaft 3, and Spring shaft 3 to leaf spring 5
And is distributed to the drive shaft axle housing 8 side and the driven shaft axle housing 10 side, respectively, in inverse proportion to the ratio of the distance B to the contact point of the driven shaft axle housing 10 and the drive wheel of the rear front shaft 7 and the rear rear shaft 9. , The sprung load of the leaf spring 5 is supported.

発進性を向上させうる長所がある。In the above device, when the vehicle is idle, the bent end portion 22 of the bracket 20 locks the lower surface of the rear end of the leaf spring 5, and the lower surface of the rear end of the leaf spring 5 is driven shaft axle housing 10 or driven shaft. Since it does not contact the spring seat on the upper surface of the axle housing 10, the sprung load applied to the leaf spring 5 does not act on the driven shaft axle housing 10 side,
Since the load acts on the drive shaft axle housing 8 side, the ground load on the drive wheels of the rear front shaft 7 increases, and the drive characteristics of the vehicle due to the drive wheels, particularly, the slip of the drive wheels when the vehicle starts moving, is prevented. Therefore, there is an advantage that the startability of the vehicle can be improved.

特色がある。Further, since the bracket 20 only needs to lock the lower surface of the rear end of the leaf spring 5, it can be formed in a very simple shape such as an angle material, and the side frame close to the leaf spring 5. 1, it can be easily manufactured at a low cost, and has a particularly great advantage for vehicles because of its light weight.
In addition, the above-mentioned device can be easily retrofitted to a conventional car, and thus has a feature that the practical effect is very large.

きる利点がある。Further, as described above, since the startability of the vehicle when the vehicle is idle can be improved, the distance A from the contact points of the leaf spring 5 and the drive shaft axle housing 8 to the spring shaft 3 and the spring shaft 3 to the contact point on the side of the leaf spring 5 and the driven shaft axle housing 10 with respect to the distance B to 1: 1 so that the rear front shaft 7 during loading can be reduced.
Also, there is an advantage that the axle load of the rear and rear shafts 9 can be averaged to easily increase the load of the vehicle despite the limitation of the axle load.

The mounting height of the bracket 20 can be adjusted, and furthermore, a shim 2 having an appropriate thickness is provided at the upper end in the bolt hole 24.
If the brackets 20 are inserted to prevent the height of the brackets 20 from shifting, the brackets 20 can be easily shared by different types of vehicles and the like, and errors in the shape and assembly of the leaf springs 5 can be reduced. It can be easily absorbed and is convenient on a large scale. Further, instead of the bolt hole 24 of the bracket 20, a bolt hole formed on the side frame 1 side is formed as an elongated hole extending vertically, so that a shim similar to the above is provided. It goes without saying that the same operation and effect as described above can be achieved even if the insertion is performed.

な作用効果を奏することができるものである。In each of the above embodiments, the bent end portion 22 of the bracket 20 locks the lower surface of the rear end of the leaf spring 5 when the vehicle is idle, so that the lower surface of the rear end of the leaf spring 5 and the driven shaft axle housing 10 side However, when the vehicle is empty, the bent end portion 22 of the bracket 20 is locked on the lower surface of the rear end of the leaf spring 5 and the lower surface of the rear end of the leaf spring 5 and the driven shaft axle housing. By reducing the contact force of the lower surface of the rear end of the leaf spring 5 with respect to the driven shaft axle housing 10 even when the driven shaft 10 contacts, the load acting on the driven shaft axle housing 10 can be reduced accordingly.
Even if an extra load acts on the drive shaft axle housing 8 side by the reduced amount, the same operation and effect as those of the above embodiments can be obtained.
