Abstract
The utility model discloses a gearbox auxiliary supporting assembly which comprises a support, a leaf spring, an adjusting plate and abrasion-resistant plates. The middle of the leaf spring is connected with a gearbox through the adjusting plate, two ends of the leaf spring are respectively directly freely located on the two abrasion-resistant plates, the two abrasion-resistant plates are respectively fixed on the upper surface of the support, and the support is fixed on a vehicle frame. Due to the fact that the leaf spring is freely located on the abrasion-resistant plates, casing crack caused by excessive constraint of the gearbox and an engine can be avoided. Due to the fact that the abrasion-resistant plates are adopted against friction with the leaf spring, the service life of the support is prolonged, and accordingly the maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of automotive field, particularly relates to a kind of haul truck transmission auxiliary support assembly.
Background technology
Transmission auxiliary support assembly belongs to chassis assembly, plays a part to support and protection change speed gear box, and the situation of its design directly affects the service life of change speed gear box, and main supplemental support has following three kinds at present:
1, driving engine, change speed gear box are rack-mount by Rubber shock-absorbing pad after linking together by adapter plate.
2, change speed gear box is directly connected with crossbeam, and crossbeam is bolted at the support by Rubber shock-absorbing pad and vehicle frame.
3, change speed gear box is connected with crossbeam by Rubber shock-absorbing pad, crossbeam with vehicle frame on support be bolted.
Above connection way respectively has shortcoming separately, and the 1st kind due to the whole rear overhang of change speed gear box, running into operating mode severe in the situation that, easily causes gear box casing, flywheel shell of engine etc. to break; When service engine or change speed gear box, need driving engine and change speed gear box integral demounting, work capacity is large.2nd, 3 kinds of parts are many, easily make change speed gear box, driving engine produce Over-constrained and housing is broken.
In view of this, the inventor, for the above-mentioned defect in-depth study of existing transmission auxiliary support assembly, has this case to produce then.
Utility model content
The purpose of this utility model is to provide a kind of transmission auxiliary support assembly, to solve existing transmission auxiliary support, easily produces Over-constrained and housing is broken and part is many, high in cost of production problem.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of transmission auxiliary support assembly, and it comprises bearing, sheet spring, adjusts plate and wear plate; Described sheet spring middle part is connected with change speed gear box by adjusting plate, and the two ends of sheet spring are directly freely seated on two wear plates respectively, and two wear plates are separately fixed at the upper surface of bearing, and bearing is fixed on vehicle frame.
Described sheet spring and adjust between plate, adjust between plate and change speed gear box and all adopt bolt to be rigidly connected, between sheet spring and support, sheet spring and change speed gear box all without Rubber shock-absorbing pad.
Described wear plate is fixed together by bolt and bearing.
Adopt after such scheme, the utlity model has following advantage:
One,, because of the present utility model spring is freely seated on wear plate, can avoid the Over-constrained of change speed gear box, driving engine and housing is broken.
Two, due to the utility model, reduced the parts such as rubber pad, avoided the vibration damping that ageing of rubber etc. causes to lose efficacy, and reduced costs;
Three, because the utility model adopts wear plate and the friction of sheet spring, extended the life-span of bearing, thereby reduced maintenance cost.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is axonometric drawing of the present utility model;
Fig. 2 is front elevation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of transmission auxiliary support assembly, and it comprises bearing 1, sheet spring 2, adjusts plate 3 and wear plate 4.
Described sheet spring 2 middle parts are connected with change speed gear box 10 by adjusting plate 3, and the two ends of sheet spring 2 are directly freely seated on two wear plates 4 respectively, and two wear plates 4 are separately fixed at the upper surface of bearing 1 by bolt, and bearing 1 is fixed on vehicle frame.
In the present embodiment, sheet spring 2 and adjust between plate 3, adjust between plate 3 and change speed gear box 10 and all adopt bolt to be rigidly connected, does not all adopt Rubber shock-absorbing pad between sheet spring 2 and bearing 1, sheet spring 2 and change speed gear box 10.
The effect of each parts of the utility model:
Adjusting plate 3, is in order to correct because of processing, the error causing to be installed, making the suffered quiet moment of flexure of actual pre compressed magnitude and change speed gear box 10 consistent.
Wear plate 4, adopts high-abrasive material to make, and mainly bears sheet spring 2 in the friction of bearing 1, extends the life-span of bearing 1, and wear plate 4 employings are detachable, can change according to the situation of wearing and tearing, thereby greatly reduce maintenance cost.
The size of bearing 1, wear plate 4 is determined according to the size of sheet spring 2.
Emphasis of the present utility model is just: sheet spring is freely seated on bearing.
The above, it is only the utility model preferred embodiment, the connection mode of wear plate and bearing can have multiple, therefore can not limit the scope that the utility model is implemented with this, the equivalence done according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (3)
1. a transmission auxiliary support assembly, is characterized in that: it comprises bearing, sheet spring, adjusts plate and wear plate; Described sheet spring middle part is connected with change speed gear box by adjusting plate, and the two ends of sheet spring are directly freely seated on two wear plates respectively, and two wear plates are separately fixed at the upper surface of bearing, and bearing is fixed on vehicle frame.
2. transmission auxiliary support assembly as claimed in claim 1, is characterized in that: described sheet spring and adjust between plate, adjust between plate and change speed gear box and all adopt bolt to be rigidly connected.
3. transmission auxiliary support assembly as claimed in claim 1, is characterized in that: described wear plate is fixed together by bolt and bearing.
