Description
Technical field
The utility model relates to a kind of transmission auxiliary support assembly, belongs to automotive transmission technical field.
Background technology
At present, the transmission auxiliary support of heavy motor vehicle is generally be connected by connecting panel and change speed gear box two bolts, connecting panel is connected by rubber block and a backing plate and elastic beam bolt, the elastic beam left and right sides is connected with frame inside face by bracket, after elastic beam has assembled, two ends are attached on two lateral brackets.The shortcoming of this scheme is: be connected by a rubber block bolt between connecting panel with elastic beam, and when vehicle pitch change speed gear box wigwag motion, elastic beam easily rotates and comes off from left and right bracket, and torsional strength is more weak; Because rubber block easily produces compressive deformation, thus produce gap between elastic beam and rubber block, add the stressed of elastic beam, also easily cause tie bolt be subject to the effect of friction stress and cut off simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of rational in infrastructure, the transmission auxiliary support assembly that can effectively prevent elastic beam from rotating.
For solving this technical matters, the utility model provides a kind of heavy motor vehicle transmission auxiliary support assembly, comprise elastic beam, connecting panel and bracket, described elastic beam is strip, both sides are provided with lower bending, two bolts hole one are provided with in the middle part of it, described connecting panel is arch shape, upper surface, middle part is provided with two bolts hole two concentric with elastic beam, its two ends are provided with connecting bore, the backing plate that at least one piece is provided with concentric holes is set between described elastic beam and connecting panel, elastic beam, backing plate and connecting panel are linked into an integrated entity by screw bolt and nut, the lower surface of described connecting panel is connected with change speed gear box by connecting bore bolt, described elastic beam two ends abut in be fixed on frame inside face bracket on.
Described bracket is provided with angle of inclination.
Described elastic beam adopts leaf spring 50CrVA to make.
Beneficial effect: the utility model adopts elastic beam form can increase substantially torsional strength and damping effect, elastic beam material adopts leaf spring material, connecting panel is all at 2 with elastic beam and change speed gear box and is connected, impact can be alleviated like this when change speed gear box shakes, prevent from elastic beam from producing torsion to come off from left and right bracket, add the torsional strength of this assembly, and extend the service life of auxiliary supporting device for gearbox.The utility model is rational in infrastructure, easy to assembly, production efficiency is high, torsional strength is high, can effectively prevent elastic beam from rotating.
