Abstract
The utility model relates to a heavy-duty vehicle axle of a single hydraulic motor, which comprises an axle shaft, half axles and a wheel speed reducer, wherein, a central transmission assembly is arranged on the axle shaft, a gear box is arranged on the casing of the central transmission assembly, a hydraulic motor is arranged outside the gear box, a driving gear and a driven gear meshed with the driving gear are arranged on the inner wall inside the gear box, the hydraulic motor is connected with the driving gear, a driving hypoid spiral bevel gear is fixed on the driven gear, a driven hypoid spiral bevel gear meshed with the driving hypoid spiral bevel gear is arranged in the central transmission assembly, a differential is fixed in the driven hypoid spiral bevel gear, half-axle connectors are arranged on the left and the right sides of the differential respectively, and the two half axles are fixed on the corresponding half-axle connectors respectively. The utility model has the advantages that only one hydraulic motor can be installed on each driving axle, the cost of the products is reduced, and the hydraulic motor is an exposed part, therefore, the disassembly and the installation are simple, and the cleaning and the maintenance are easy.
Description
Technical field
The utility model relates to the heavy vehicle bridge that a kind of heavy carrier loader uses vehicle bridge, particularly a kind of single HM Hydraulic Motor.
Background technology
Drive axle is the important component part of vehicle, is also referred to as vehicle bridge.Existing heavy carrier loader as hydraulic power flat bed transport vehicle and module power flat bed transport vehicle, generally is to be driven by a plurality of relatively independent vehicle bridge.The mechanically operated vehicle bridge of traditional usefulness is difficult to arrange a plurality of relatively independent vehicle bridge simultaneously that therefore, the vehicle bridge that heavy carrier loader uses is generally uses hydraulicdriven drive axle.
Hydraulicdriven drive axle main body of the prior art is a bridge axle, bridge axle two ends respectively are provided with one group of driver element, all be provided with HM Hydraulic Motor and wheel side speed reducer in each driver element, the driving engine of vehicle drives Hydraulic Pump, power is passed to each HM Hydraulic Motor, and HM Hydraulic Motor gives wheel side speed reducer with drive wheels transmission of power.The HM Hydraulic Motor of drive axle is installed in the bridge axle, and the installation of HM Hydraulic Motor and removal are all pretty troublesome, is difficult to safeguard; Each drive axle needs two cover driver elements, and heavy carrier loader needs 6-10 cover driver element, and driver element mostly is imported components, costs an arm and a leg, and delivery cycle is long, has both raised product cost, has limited production efficiency again.
Summary of the invention
The purpose of this utility model provides a kind of heavy vehicle bridge, can effectively solve problems such as installation that prior art exists and removal trouble, difficult in maintenance and cost height.The utility model relates to a kind of heavy vehicle bridge of single HM Hydraulic Motor, comprise the bridge axle, two semiaxis in the bridge axle, bridge axle two ends are respectively equipped with a wheel side speed reducer, it is characterized in that: the bridge axle is provided with the main gear assembly, main gear assembly shell is provided with drop-gear box, drop-gear box is provided with a HM Hydraulic Motor outward, sidewall in the drop-gear box is provided with a driving gear and a ring gear that is meshed with driving gear, HM Hydraulic Motor is connected with driving gear, be fixed with an initiatively hypoid screw bevel gear on the ring gear, be provided with a passive hypoid screw bevel gear in the main gear assembly, passive hypoid screw bevel gear is meshed with active hypoid screw bevel gear, be fixed with diff in the passive hypoid screw bevel gear, both sides, the diff left and right sides are respectively equipped with a semiaxis interface, and two semiaxis are separately fixed on the cooresponding semiaxis interface.One section of described semiaxis is fixed on the semiaxis interface, and the other end of semiaxis is connected with a wheel side speed reducer.Described active hypoid screw bevel gear is provided with umbrella handle, and initiatively the umbrella handle of hypoid screw bevel gear is connected with ring gear, and the junction of umbrella handle and ring gear is provided with a spline.Advantage of the present utility model is: each drive axle is only installed two wheels that a HM Hydraulic Motor can drive a group, has reduced cost of product, and HM Hydraulic Motor is the parts that expose, and removes and installs simply, is easy to cleaning and safeguards.
Description of drawings
Accompanying drawing 1 is the drive axle structural representation of prior art,
Accompanying drawing 2 is an integral structure scheme drawing of the present utility model,
Accompanying drawing 3 is drop-gear box of the present utility model and main gear assembly in-to-in structural representation.
The specific embodiment
The utility model at work, the drop-gear box external hydraulic pressure motor starts, and drives drop-gear box in-to-in driving gear and rotates, and then the ring gear rotation that is meshed with driving gear of drive; Be fixed with an initiatively hypoid screw bevel gear on the ring gear, initiatively the hypoid screw bevel gear can be driven to rotate; Passive hypoid screw bevel gear is meshed with active hypoid screw bevel gear, and passive hypoid screw bevel gear can be driven to rotate; Be fixed with diff in the passive hypoid screw bevel gear, both sides, the diff left and right sides are respectively equipped with a semiaxis interface, and two semiaxis are separately fixed on the cooresponding semiaxis interface.One section of described semiaxis is fixed on the semiaxis interface, the other end of semiaxis is connected with a wheel side speed reducer, wheel is installed on the wheel side speed reducer, power is transferred into two wheel side speed reducers respectively, two wheel side speed reducers drive a wheel respectively, the wheel on both sides can obtain different cireular frequencys on the same drive axle, final two wheel that drive on the same group.
A HM Hydraulic Motor just can drive two wheels on the same group, and therefore parts such as while main gear assembly in-to-in driving gear are also reduced, and can reduce production costs significantly; HM Hydraulic Motor is to be positioned at the bridge axle originally in the prior art, removes and installs difficulty, troublesome maintenance, and the HM Hydraulic Motor in the utility model is the parts that expose, and removes and installs cleaning easily; Make full use of the motion characteristics of diff in the utility model, the wheel on both sides can obtain different cireular frequencys on the same drive axle, every group of wheel all has the drive system of oneself, be applied to easily to realize the multiple pattern that turns on the Oversize vehicle, as straight-going mode, diagonal pattern, walk crosswise pattern, yaw pattern, the pattern of wagging the tail, the Eight characters and turn to pattern, cast pattern etc.
