Abstract
The utility model relates to a lifting device, in particular to an automobile axle lifting device, which aims to solve the problems of the most prior vehicles during no load running process such as all land-hit tires, massive power loss, lower no load running speed, higher oil consumption, and faster abrasion of the tires. The utility model is characterized in that a crank shaft is arranged in a crank shaft box, a gear is fixedly connected with a crank of the crank shaft, a rope pulley is arranged at the free end of the crank shaft, a tooth rack is arranged in a tooth rack skid road, the tooth rack is meshed with the gear, threads matched with a screw rod are formed in the tooth rack, and one end of a steel wire rope is connected with an automobile truck beam while the other end thereof is connected with the rope pulley. The utility model is mounted in a steel tank of the automobile truck beam, thereby utilizing the space skillfully. The large load is changed into small torque through such mechanisms as the crank shaft, the screw rod, a reducer and the like, the rear axle can be self-locked after being lifted by the crank shaft to avoid elastic recovery, and the crank shaft can transfer the impaction from the steel wire rope to the automobile truck beam through a limitation stop, thereby avoiding the whole mechanism from being damaged.
Description
Technical field
The utility model relates to a kind of bont.
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 automotive axle bont is provided.
The utility model is made up of power system and elevator system, elevator system is two, respectively by turning axle, turn axle casing, rack slide, screw rod, tooth bar, gear, rope sheave, positive stop, limit switch, steel rope and passive sprocket wheel are formed, turning axle is arranged on and turns in the axle casing, gear is captiveed joint with the crank that turns axle, rope sheave is arranged on the free end that turns axle, rack slide is fixed on the lower end of turning in the axle casing, tooth bar is arranged in the rack slide, rack and pinion is meshed, screw rod is arranged in the tooth bar, be provided with the screw thread that matches with screw rod in the tooth bar, be fixed with by movable sprocket on one end of screw rod, one end of steel rope is connected with automotive frame, the other end of steel rope is connected with rope sheave, positive stop is fixed on above the automotive frame that turns upper end in the axle casing, limit switch is fixed on turning on the axle casing of rack slide afterbody, power system comprises electrical motor, change-speed box, two drive sprockets and two chains, the output shaft of electrical motor is connected with the input end of change-speed box, be connected with two drive sprockets on the mouth of change-speed box, two drive sprockets are connected with two passive chain sprocket drive respectively by two chains.
Principle of work of the present utility model: retarder reduces the revolution of electrical motor, and the torque increasing drives tooth bar and moves along slideway after chain gear is rotated screw rod, and tooth bar promotes the gear rotation, and gear driven turns axle and rotates, and by steel rope back axle is mentioned.
The beneficial effects of the utility model: one, power system and elevator system all are installed in the steel tank of automotive frame, ingenious this space that utilized.Two, by turning mechanisms such as axle, screw rod, retarder big load is become little torque, so use small power motor just can work.Three, turn axle and will can self-locking avoid resilience after the back axle lifting, turn axle and can pass to automotive frame, avoid damaging entire mechanism passing through positive stop from the impact of steel rope.Four, 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.
