Description

Truck is with balanced suspension

Technical Field

The utility model relates to an automobile parts field especially relates to a balanced suspension is used to truck.

Background

If two axles (e.g., the center axle and the rear axle of a three-axle vehicle) are mounted at both ends of the stabilizer bar and the center of the stabilizer bar is hingedly connected to the frame, raising one axle lowers the other axle. Moreover, because the two arms of the balancing rod are equal in length, the vertical loads of the two axles are equal under any condition, and the suspension condition of individual wheels cannot be generated. This type of suspension, which ensures equal vertical loading of the wheels of the middle and rear axles, is called a balanced suspension.

The balance suspension that the present market was used for the truck is in the use, settles bearing hub on the balance shaft and can rub with balance shaft support, can produce wearing and tearing and cause not hard up, and then reduces practical life and has the potential safety hazard.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art and providing a balanced suspension for a truck.

The balance suspension for the truck is characterized by comprising a balance shaft support, a balance shaft shell, a rubber bushing, a gasket, a dust cover and a bolt, wherein the balance shaft support can be divided into a balance shaft and a suspension base, the balance shaft is perpendicular to the suspension base, the balance shaft shell is sleeved on the balance shaft, the rubber bushing is arranged between the balance shaft shell and the balance shaft, the gasket is arranged between the balance shaft shell and the suspension base, the gasket is sleeved on the balance shaft, the dust cover is arranged at the end part of the balance shaft, and the bolt fixes the dust cover.

Preferably, the balance shaft support is cast by using integral ductile iron.

Preferably, the balance shaft shell is divided into a balance shaft shell upper cover and a balance shaft shell lower cover, and protruding parts and fixing holes are arranged on two sides of the balance shaft shell.

Preferably, the balance shaft support is provided with an upper reaction force base and a lower reaction force base, the lower reaction force base is protruded in the direction of the balance shaft and is perpendicular to the balance shaft support, and the upper reaction force base and the lower reaction force base are opposite in direction.

Preferably, the upper end of the balance shaft support is provided with a support base, the support base is symmetrical about the vertical plane of the balance shaft, and the support base is provided with a plurality of through holes.

Preferably, the inner ring and the outer ring of the rubber bushing are provided with protruding parts, and the protruding parts are matched with the balance shaft and the balance shaft shell.

The utility model has the advantages that:

through the scheme of integral iron ball casting and machining, the assembly error of the assembled suspension is avoided, and meanwhile, the weight is reduced and the precision is improved; a gasket is arranged between the balance shaft shell and the balance shaft support, so that abrasion between the balance shaft shell and the balance shaft support is avoided, and the service life is prolonged; the rubber bushing is arranged between the balance shaft and the balance shaft shell, so that the buffer effect is achieved, and the friction between the balance shaft and the balance shaft shell can be avoided.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1 to 3, a balance suspension for a truck includes a balance shaft bracket 1, a balance shaft case, a rubber bush 5, a washer 2, a dust cap 6, and a bolt 4. The balance shaft support 1 can be divided into a balance shaft 8 and a suspension base 9, the balance shaft 8 is perpendicular to the suspension base 9, and a balance shaft shell is sleeved on the balance shaft 8. Be equipped with rubber bush 5 between balanced axle housing and the balanced axle 8, be equipped with packing ring 2 in the middle of balanced axle housing and the suspension base 9, packing ring 2 cup joints on balanced axle 8. The balance shaft shell is divided into a balance shaft shell upper cover 3 and a balance shaft shell lower cover 7, and protruding parts and fixing holes are arranged on two sides of the balance shaft shell. The end part of the balance shaft 8 is provided with a dustproof cover 6, and the dustproof cover 6 is fixed by the bolt 4.

In use, the balance shaft shell can rotate around the balance shaft 8, and the rubber bushing 5 can reduce the abrasion between the balance shaft shell and the balance shaft 1. The balance shaft shell is divided into a balance shaft shell upper cover 3 and a balance shaft shell lower cover 7, and the balance shaft shell is fixed through fixing holes formed in the protruding parts on the two sides. The utility model discloses balance shaft 8 and suspension base 9 are a whole, and balance shaft support 1 is through whole casting and machining promptly for whole main part simple structure, whole precision obtains improving, has avoided the maintenance cost and the time of user in the use.
