Description

Load-carrying vehicle vehicle bridge thrust lever apparatus

Technical field

This utility model is related to a kind of thrust lever apparatus, specifically a kind of load-carrying vehicle vehicle bridge thrust lever apparatus.

Background technology

During load-carrying vehicle is travelled and turned, vehicle bridge may produce the problem of left and right sidesing shifting, cause leaf spring to produce with tire Raw friction, can cause the tire severe accident that early mill is even blown out when serious, therefore on the chassis of load-carrying vehicle, in order to anti- Only vehicle bridge displacement, it will usually installed thrust lever apparatus, the heavy vehicle of early development typically adopts Dan Shangzhi distance rod structures, car Frame end propelling rod support is arranged in frame cross, and the power of distance rod needs to pass to longeron through crossbeam.But with tonnage Be continuously increased, easily occur upper thrust rod fracture, crossbeam tear, distance rod and crossbeam connecting bolt loosen, the failure such as fracture, And it is inadequate for cross force conduction, therefore adopt V-type distance rod mostly at present.However, V-type distance rod is received with the junction point of vehicle bridge Power is larger, and manufacturing cost is higher, and processing technique is complex for the processing technique of straight thrust, particularly the thrust One end that bar is in the shape of the letter V, will adopt solid forging technology during processing and manufacturing, and mould processing is relatively complicated, so as to Manufacturing cost is increased, and installing/dismounting is also very laborious；In addition, usual distance rod is to be arranged on vehicle bridge by hold-down support On vehicle frame, but, when distance rod stress unstable due to the reason such as road conditions vehicle traveling, bearing and vehicle bridge can be produced very big Active force, when strength is excessive, in addition can directly destroy connector and damage vehicle bridge.

The content of the invention

For above-mentioned prior art exist problem, the purpose of this utility model be to provide one kind can reduce fault rate, Low cost, it is easy for installation, ensure that distance rod stable connection, guarantee that vehicle bridge is injury-free, it is ensured that normally travel safety Load-carrying vehicle vehicle bridge thrust lever apparatus.

For achieving the above object, the technical solution adopted in the utility model is：A kind of load-carrying vehicle vehicle bridge thrust lever apparatus, bag Axle housing is included, axle housing is symmetrically arranged on two with distance rod structure, and the distance rod structure includes upper thrust rod and lower thrust Bar, the upper thrust rod and lower thrust rod are arranged on axle housing respectively by hold-down support；The hold-down support bottom is Fixing card and portion, the fixing card and portion include wrapping up the clamp of axle housing from both sides, and on the clamp per side spiral shell is all provided with Pit, hold-down support top is distance rod erecting bed, and distance rod erecting bed includes the location hole of locating slot and locating slot both sides.

Further, the hold-down support surface side of the upper thrust rod is provided with buffer part.

Preferably, the buffer part is hollow column buffer stopper.

In load-carrying vehicle upper thrust rod device described in the utility model, the first and second straight distance rod is respectively by a ball Pin is connected with the distance rod bridge upper bracket, and the increase of the ball pin quantity causes the active force that the ball pin can bear to carry significantly Height, so as to efficiently reduce the possibility that the straight distance rod ball pin breaks down；Meanwhile, the technique for also reducing processing and manufacturing is difficult Degree and manufacturing cost；Further, since the load-carrying vehicle upper thrust rod device is constituted and divided by two independent straight distance rods It is not installed on frame cross and distance rod bridge upper bracket, installs more convenient, and for vehicle frame and the precision of crossbeam size Requirement also decreases, relatively low so as to solve the problems, such as load-carrying vehicle upper thrust rod device adaptability.

Upper and lower distance rod of the present utility model is symmetrically connected on axle shell respectively by propelling rod support, balance More preferably, disperse the stress of axle housing, reduce the possibility for breaking down；Reduce difficulty of processing and cost, each unit construction peace Dress, required precision is not high, and dismounting and change is convenient, and the design of propelling rod support makes screw share distance rod and gives upper and lower thrust The power of bearing and axle housing weld seam, strengthens the bonding strength of upper and lower thrust bearing and axle case assy, reduces upper and lower thrust The risk that seat and axle housing are damaged, allows propelling rod support effectively to realize the biography of brake force and pull strength and counteracting force Pass, increased weld seam push away in distance rod, the rigidity drawn on direction, so as to extend service life, it is ensured that normally travel safety. This device is practical, and installing/dismounting changes convenient, reduces maintenance cost.

Specific embodiment

This utility model is described in further detail below in conjunction with the accompanying drawings.

As illustrated, a kind of load-carrying vehicle vehicle bridge thrust lever apparatus, including axle housing 10, the both sides of axle housing 10 symmetrically set There is distance rod structure, the distance rod structure includes upper thrust rod 20 and lower thrust rod 30, the upper thrust rod 20 and lower thrust Bar 30 is arranged on axle housing 10 respectively by hold-down support 40；The bottom of the hold-down support 40 is fixing card and portion, described Fixing card and portion include wrapping up the clamp 41 of axle housing 10 from both sides, and on the clamp 41 per side screwed hole 42 is all provided with, Gu It is distance rod erecting bed 43 to determine the top of bearing 40, and distance rod erecting bed 43 includes the positioning of locating slot 431 and the both sides of locating slot 431 Hole 432.

Further, for the up-down vibration that can effectively buffer and limit vehicle frame when vehicle jolts, the lifting force The surface side of hold-down support 40 of bar 20 is provided with buffer part 44.

Preferably, in order to ensure to buffer the effect with damping, the buffer part 44 is hollow column buffer stopper.

When using, screw 50 passes through screwed hole 42 from the both sides in fixing card and portion, and certain moment of torsion is applied to screw 50, will Up and down both sides of the Primary Location of hold-down support 40 at the two ends of axle housing 10；Again plug welding is carried out to each screwed hole 42, so as to incite somebody to action Clamp 41 is securely joined together with axle housing main body 10, and the mounting head 60 of upper thrust rod 20 and the one end of lower thrust rod 30 is put respectively In the locating slot 431 of relevant position propelling rod support, bolt 70 is each passed through installing hole 61 and locating slot in mounting head 60 The location hole 432 of 431 both sides, mounting head 60 is fixed on distance rod erecting bed 43, so as to upper and lower distance rod passes through distance rod Bearing is symmetrically connected on axle shell body 10, and upper and lower distance rod is arranged symmetrically, and balance is more preferable, and multiple junction points point The stress of axle housing has been dissipated, the possibility for breaking down has been reduced；Component processing is convenient, reduces difficulty of processing and cost；Each part Combination is installed, and installation accuracy is less demanding, and dismounting and change is convenient, and the design of propelling rod support makes screw share distance rod to give The power of upper and lower thrust bearing and axle housing weld seam, strengthens the bonding strength of upper and lower thrust bearing and axle case assy, increased Weld seam is pushed away in distance rod, the rigidity drawn on direction, reduces the risk that upper and lower thrust bearing and axle housing are damaged, can be effective Realize the transmission of distance rod brake force and pull strength and counteracting force.
