U-shaped bolts and automobile with same

Abstract

The invention discloses U-shaped bolts. Treads of two straight bars of each U-shaped bolt have opposite spiral directions. The invention also discloses an automobile comprising an axle and a plate spring, wherein the automobile also comprises the U-shaped bolts and nuts, the nuts are matched with the U-shaped bolts, and the plate spring is fixed on the axle by the U-shaped bolts and the nuts. Because the threads of the two straight bars of each U-shaped bolt have the opposite spiral directions, the opposite threads can be used for balancing force moments generated by fastening the nut, thereby angles can not be formed among fixed parts, and the fixed parts can not be deformed. The plate spring can be vertically fixed on the axle when being fixed on the axle by using two U-shaped bolts, therefore, the automobile has better brake performance and better steering flexibility, and the U-shaped bolt can reduce tyre wear, fuel consumption, and the like and is convenient for the subsequent installation of the automobile.

Description

technical field [0001] The invention relates to a U-shaped bolt, and also relates to an automobile with the U-shaped bolt. Background technique [0002] U-shaped bolts, also known as saddle bolts, are widely used, for example, two U-shaped bolts are usually used to fix the leaf spring of the car suspension to the axle. The threads of the two straight rods of the existing U-shaped bolts are all right-handed threads. Therefore, the tightening direction of the nuts is consistent. If the tightening torque is large, it may cause an angle to be formed between the fixed parts, or make the fixed parts Fixed parts deformed. For example, when two U-shaped bolts are used to fix the leaf spring of the automobile suspension to the axle, when the two U-shaped bolts are tightened, the four nuts are tightened in the same direction. Since the tightening torque of the U-shaped bolts is relatively large, most of which exceed 150N·M, and the direction of the tightening torques of the four str...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the existing U-shaped bolts may cause an angle to be formed between the fixed parts, or the fixed parts may be deformed; and the existing U-shaped bolts are used to fix the leaf spring to the axle When it is on, it will cause an angle between the leaf spring and the axle, which will affect the braking performance and steering flexibility of the vehicle. It will also increase tire wear and fuel consumption, and will also bring difficulties to the subsequent installation of the vehicle.
