Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1, the multi-pull-rod suspension mechanism for the mining man car comprises two vehicle suspension systems (a front axle 1a and a rear axle 1b) arranged at the bottom of a frame, wherein an upper clamping plate 2 and a lower clamping plate 3 which are fixed together are arranged on two sides of each vehicle suspension system, a shock absorption assembly 5 which supports the frame upwards is arranged on each lower clamping plate 3, a lower pull rod 4a which is rotatably connected to the side of the frame is further arranged on each lower clamping plate 3, a longitudinal pull rod 4b which is rotatably connected to the middle of the frame is arranged on one upper clamping plate 2a, and a transverse pull rod 4c which is connected to the frame towards the side is arranged on the other upper clamping plate 2 b. In addition to the conventional shock absorption component 5, four connecting parts are respectively added on the front axle and the rear axle, wherein two lower pull rods 4a and a longitudinal pull rod 4b pull the frame from the front and rear directions of the vehicle, one transverse pull rod 4c pulls the frame from the left and right directions of the vehicle, when the mining man-vehicle runs on a rough road surface, the front wheel and the rear wheel cannot keep synchronous movement, so that the front axle and the rear axle can generate irregular movement from front to back and from left to right, the four shock absorption components 5 can weaken the influence of the four shock absorption components on the frame, and the eight pull rods can limit the vibration within a certain range, so that the shock absorption effect can be ensured, the comfort of drivers and passengers is improved, the customer satisfaction degree is improved, and the market competitiveness of products is improved.
As shown in fig. 2 and 3, the damper assembly 5 includes a coil spring 51, a damper 52 located inside the coil spring 51, and a wire rope 53 located at a side of the coil spring 51. The coil spring 51 can be selected from springs with lower rigidity and longer stroke, the damping assembly 5 can adapt to the working condition environment with more fluctuation in a mine, the vibration caused by the coil spring 51 can be further attenuated by the damper 52, and the steel wire rope 53 is responsible for limiting the farthest distance between the lower clamping plate 3 and the frame to prevent the upper end of the coil spring 51 from being disengaged.
As shown in fig. 1 and 4, rubber cores 6 are arranged at two ends of the lower pull rod 4a, the longitudinal pull rod 4b and the transverse pull rod 4c, each rubber core 6 comprises a mandrel 61 with an expanded middle part, rubber 62 wrapping the expanded part of the mandrel 61 and two retaining rings 63 located outside the rubber 62, and the retaining rings 63 are penetrated through two ends of the mandrel 61. The two ends of the spindle 61 are fixed to the frame or the vehicle suspension system, and the retainer ring 63 is fixed to the tie rod (the lower tie rod 4a, the longitudinal tie rod 4b, or the cross tie rod 4 c). The mandrel 61 and the collar 63 are rigid, while the rubber 62 is elastic. The elasticity of the rubber 62 enables the spindle 61 to swing within a certain range, for example, 10 ° forward and backward and 15 ° up and down, relative to the retainer 63. Therefore, the degree of freedom of a vehicle suspension system can be increased, the vibration reduction effect is improved, and the working condition of a mine can be better met.
As shown in fig. 1, the trailing arm 4b of the front axle 1a and the trailing arm 4b of the rear axle 1b are in a diagonal relationship of the vehicle, and the track rod 4c of the front axle 1a and the track rod 4c of the rear axle 1b are on the other diagonal of the vehicle. This arrangement better addresses the crossed axle situation where only a pair of diagonal wheels fully land.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
