Abstract

The utility model discloses a lifting device of a screw type automobile axle, relating to a lifting device of a screw type automobile axle and aiming at solving the problems that when most existing vehicles runs without load, all tires are landed, so the problems of large power loss, reduction of idle running speed, increasing of oil consumption and accelerating of the wear of the tires exist. In the lifting device, a first driving chain wheel and a second driving chain wheel are respectively connected with an output shaft of a motor; a first chain is respectively connected with the first driving chain wheel and a lifting mechanism in a transmission manner; and a second chain is respectively connected with the second driving chain wheel and another lifting mechanism in a transmission manner. The lifting mechanism lifts a rear axle and then can be self-locked, so as to lead the rear axle to be incapable of falling. The lifting device is simple in structure, small in volume and fast in response, lifts the axle when in need, and leads the tires not to be contacted with the ground, thus reducing the friction of the tires and the ground, reducing the wear of the tires and power loss of an engine, and being capable of reducing oil consumption and operating cost.

Background technology

Existing transport truck is in order to satisfy the requirement of drawing manyly, running a good foot, cutting operating costs, the various multiple shafting train types of the numerous and confused release of each producer, the axle load of these vehicles distributes rationally, load-carrying capacity is big, stationarity good, propulsive effort and braking force are big, but most of vehicles are when deadhead operation, all tire all lands, and exists a large amount of watt losss, and therefore having reduced sky sails speed, increase oil consumption, quickened Tyte Wear.

The utility model content

The purpose of this utility model is for solving existing most of vehicles when the deadhead operation, and all tire all lands, and exists a large amount of watt losss, reduce sky and sailed speed, increased oil consumption, quickened the Tyte Wear problem, a kind of screw automotive axle bont is provided.

The utility model comprises two lift systems, first chain, second chain and main drive gear, main drive gear is made up of electrical motor, first drive sprocket and second drive sprocket, first drive sprocket all is connected with the output shaft of electrical motor with second drive sprocket, first chain is in transmission connection with first drive sprocket and a lift system respectively, and second chain is in transmission connection with second drive sprocket and another lift system respectively.

The beneficial effects of the utility model: one, two lift systems all are installed in the steel tank of automobile chassis frame, have rationally utilized this space.Two, can self-locking after lift system promotes back axle, make the back axle can not free fall.Three, the utility model is simple in structure, volume is little, response is fast, in needs, relevant vehicle bridge is raised up, tire is no longer contacted with ground, thereby tire and ground-surface friction have been reduced, reduced the watt loss of Tyte Wear and driving engine, can reduce oil consumption and can cut operating costs again.

Description of drawings

Fig. 1 is an integral structure scheme drawing of the present utility model, Fig. 2 be the A of Fig. 1 to view, Fig. 3 be the B of Fig. 1 to view, Fig. 4 is the scheme drawing that lifting arm 4-1 drops to lowest part, Fig. 5 is the structural representation of the specific embodiment four, Fig. 6 is the C-C cutaway view of Fig. 5.Reference numeral 9 among the figure is a brake pump.

The specific embodiment

The specific embodiment one: (referring to Fig. 1～Fig. 6) present embodiment comprises two lift systems 4, first chain 5, second chain 6 and main drive gear 8, main drive gear 8 is made up of electrical motor 8-1, the first drive sprocket 8-2 and the second drive sprocket 8-3, the first drive sprocket 8-2 all is connected with the output shaft of electrical motor 8-1 with the second drive sprocket 8-3, first chain 5 is in transmission connection with the first drive sprocket 8-2 and a lift system 4 respectively, and second chain 6 is in transmission connection with the second drive sprocket 8-3 and another lift system 4 respectively.Two lift systems 4 are installed in respectively on the vehicle frame 1 of automobile both sides, and two lift systems 4 are connected with automobile axle 2 respectively, and crossbeam 7 is fixed on the vehicle frame 1, and main drive gear 8 is fixed on the crossbeam 7.Described electrical motor 8-1 can have pneumatic motor or fluid power motor to replace.

The specific embodiment two: each lift system 4 of (referring to Fig. 1) present embodiment is formed by lifting arm 4-1, spiral shell wheel 4-2, sprocket wheel 4-3, last block set 4-4, following block set 4-5, clamp 4-6 and short screw 4-7, spiral shell wheel 4-2 is fixed between block set 4-4 and the following block set 4-5, sprocket wheel 4-3 is fixed on the surface of spiral shell wheel 4-2, short screw 4-7 is arranged in the spiral shell wheel 4-2, lifting arm 4-1 is plugged in the short screw 4-7, the top of lifting arm 4-1 is fixed with clamp 4-6, the upper end of short screw 4-7 is provided with draw-in groove 4-8, and the draw-in groove 4-8 on clamp 4-6 and the short screw 4-7 matches.The sprocket wheel 4-3 of present embodiment matches with first chain 5 or second chain 6.The lower end of lifting arm 4-1 is connected with automobile axle 2.Other are identical with the specific embodiment one.

The specific embodiment three: the lower end of (referring to Fig. 2) present embodiment lifting arm 4-1 is a bulb-type 3.This bulb shape can make between lifting arm 4-1 and the automobile axle 2 and freely rotate.Other are identical with the specific embodiment two.

The specific embodiment four: (referring to Fig. 5 and Fig. 6) present embodiment has increased by two reinforced plates 10, and each reinforced plate 10 is fixed on the outside of a lift system 4, and the open end of reinforced plate 10 is captiveed joint with vehicle frame 1.Other are identical with the specific embodiment one, two or three.

Principle of work: after the electrical motor 8-1 energising, the first drive sprocket 8-2 and the second drive sprocket 8-3 just drive first chain 5 and second chain 6 produces the power of transmission, the power of this transmission drives sprocket wheel 4-3 and rotates, sprocket wheel 4-3 drives spiral shell wheel 4-2 and rotates, the rotation of spiral shell wheel 4-2 makes short screw 4-7 rise or descends, short screw 4-7 rising drives lifting arm 4-1 rising and has promptly promoted automobile axle 2, otherwise automobile axle 2 is descended.
