Description
Technical Field
The utility model relates to a gearbox auxiliary supporting assembly belongs to heavy-duty car technical field.
Background
At present, on a heavy-duty automobile, because a power assembly is large in mass and long in length, in order to avoid an overlarge bending moment generated on the rear end face of an engine body, an auxiliary supporting point is usually added on a gearbox, so that a five-point suspension is formed.
Disclosure of Invention
The utility model aims to solve the technical problem that to the defect that prior art exists, provide a new construction gearbox auxiliary stay assembly, improve heavy-duty car suspension and power assembly reliability.
In order to solve the technical problem, the utility model provides a gearbox auxiliary supporting assembly with high degree of freedom, which comprises a supporting beam, a pin shaft, a gearbox mounting cushion block, a sleeve, a rubber bearing, a fixed clamping block and an L-shaped bracket, wherein the rubber bearing is mounted on the gearbox mounting cushion block, the pin shaft is mounted in the rubber bearing, the sleeve is arranged between the rubber bearing and the pin shaft, the fixed clamping block is arranged outside the rubber bearing, and the rubber bearing is respectively fixed and limited in the radial direction and the axial direction through the fixed clamping block and the L-shaped bracket; the gearbox mounting cushion block is connected to the supporting beam through an L-shaped bracket.
And a groove is formed in the rubber bearing.
The axial dimension of the fixed clamping block is slightly smaller than that of the rubber bearing.
The two ends of the supporting beam are connected with an L-shaped upper connecting plate and an L-shaped lower connecting plate, and mounting holes are formed in the upper connecting plate and the lower connecting plate.
The support assembly is connected with the frame longitudinal beam through an upper connecting plate and a lower connecting plate, and the gearbox is connected with the support assembly through a gearbox mounting cushion block.
Has the advantages that: the utility model provides an in the whole four points of heavy automobile power assembly support plus five points of gearbox auxiliary stay formation support, because gearbox auxiliary stay assembly itself belongs to the setpoint, whole degree of freedom is low excessively simultaneously, easily leads to each suspension atress unbalanced to damage the problem of power assembly and suspension. Greatly reduced the fault rate of power assembly and suspension, practiced thrift the maintenance cost, improved vehicle attendance. Meanwhile, the assembly has the effect of relieving impact through deformation of the elastic body in the radial direction and the axial direction of the pin shaft, vibration transmission between the power assembly and the frame is effectively reduced, vibration noise is relieved, and riding comfort, operation stability and smoothness of the whole vehicle are improved.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a partially enlarged sectional view of a portion a in fig. 1 according to the present invention.
In the figure: 1. a frame rail; 2. an upper connecting plate; 3. a support beam; 4. a pin shaft; 5. a cushion block is arranged on the gearbox; 6. a sleeve; 7. a rubber bearing; 8. fixing the clamping block; 9. an L-shaped bracket; 10. a lower connecting plate; 11. a gearbox.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the utility model provides a gearbox auxiliary supporting assembly of high degree of freedom, including supporting beam 3, round pin axle 4, gearbox installation cushion 5, sleeve pipe 6, rubber bearing 7, fixed clamp splice 8 and L shape support 9, install rubber bearing 7 on the gearbox installation cushion 5, round pin axle 4 is equipped with in the rubber bearing 7, and rubber bearing 7 and round pin axle 4 are equipped with sleeve pipe 6 within a definite time, and rubber bearing 7 installs fixed clamp splice 8 in the outside, fixes the position limit respectively to rubber bearing 7 radial, axial through fixed clamp splice 8 and L shape support 9, effectively prevents the radial and axial displacement of rubber bearing, even the obscission that leads to because of the load of all directions; the gearbox mounting pad 5 is connected to the supporting beam 3 by an L-shaped bracket 9.
The rubber bearing 7 is internally provided with a groove with a proper size, so that a reasonable deformation avoiding space is provided for the elastic body, the friction and the impact of partial molecules in the elastic body are slowed down, the heat dissipation is reduced, and the fatigue life of the elastic body is prolonged.
The axial dimension of the fixed clamping block 8 is slightly smaller than that of the rubber bearing 7, so that the whole assembly has the effect of relieving impact through deformation of the elastic body in the radial direction and the axial direction of the pin shaft, vibration noise is effectively relieved, and the riding comfort, the operating stability and the smoothness of the whole vehicle are improved.
Two ends of the supporting beam 3 are connected with an L-shaped upper connecting plate 2 and a lower connecting plate 10, and mounting holes are formed in the upper connecting plate 2 and the lower connecting plate 10.
The support assembly is connected with the frame longitudinal beam 1 through an upper connecting plate 2 and a lower connecting plate 10, and the gearbox 11 is connected with the support assembly through a gearbox mounting cushion block 5.
The utility model discloses use the round pin axle to add rubber bearing structure, rubber bearing and round pin inter-axial installation sleeve pipe, rubber bearing passes through the fixed clamp splice to be fixed, overall structure is very firm reliable, under the prerequisite of guaranteeing that the quiet moment of flexure of engine organism rear end face and gearbox body front end face does not exceed the admissible value, adopt the round pin axle rather than traditional bolt directly to link, have higher degree of freedom, effectively solve because gearbox auxiliary supporting assembly is crossed the location and the whole degree of freedom is lower and the unbalanced problem of suspension atress that leads to, greatly reduced the fault rate of power assembly and suspension, improve the reliability; the fixed clamping blocks limit the radial direction and the axial direction of the rubber bearing, so that the whole assembly has the effect of relieving impact through the deformation of the elastic body in the radial direction and the axial direction of the pin shaft, the failure rate of the power assembly and the suspension is greatly reduced, the maintenance cost is saved, and the operation efficiency is improved
The above embodiments of the present invention are merely examples, not the only ones, and all changes within the scope of the present invention or the same range of the present invention are all surrounded by the present invention.
