Abstract

The utility model relates to an automobile driven by a bisynchronous sealing wheel fluid motive power element. Such an automobile system can be formed by using the high-efficient bisynchronous sealing wheel fluid motive power element as a main element, and in addition, the automobile system has various advantages. A hydraulic motor drives four wheels, a hydraulic pump provides motive power, and an oil path transfers the energy. Seven equivalent gradually increased gears can be provided in a serial connection mode of three pumps, the switch of a pump can adopt an electronic control mode, a press button is arranged on a steering wheel, and a traditional gear shifting handle is omitted. The utility model is characterized in that the goal of gear shifting can be reached. The conversion between two-wheel driving and four-wheel driving becomes easy. A vertical vehicle shaft can be omitted, and the differential problem does not exist, and a braking sheet can be omitted for using oil pressure braking. The utility model has the main technical scheme that a gearbox is omitted, the manufacture cost can be greatly saved, and the automobile weight can be reduced. The space in an automobile head can be released, and only an engine is in the traditional mode. The change is the revolutionary change.

Description

With two synchronous sealing wheel dynaflow part driven vehicles

Technical field

The automobile of field of vehicles.

Background technology

Automobile all has change speed gear box, axle and gear bag except driving engine, the mode of hand shift bothers, and the mechanical efficiency of autoshift is low, cost height, the space that the length of axle has limited back seat again.Can find a kind of mode of oil pressure conduction power to drive automobile sport? can constitute such system with the dynamical two wheel of sealing synchronously dynaflow parts as main element, and have many good qualities.

Summary of the invention

The technical matters that solves be the driving engine of reform traditional to the mechanical conductive pattern between the wheel, change liquid conductive power into.

Technical scheme: engine output shaft at first is connected to one surely than change speed gear box, utilize the two wheel of sealing synchronously dynaflow parts to be composed in series Hydraulic Pump for base components, on each power spare oil circuit switch is set on the Hydraulic Pump, fixed output shaft than change speed gear box is connected with the axle of Hydraulic Pump, Hydraulic Pump is connected with HM Hydraulic Motor by oil duct, brake oil duct control piece is set on the oil duct, utilizes highly pressurised liquid to constitute new automobile driving system for propulsion source; Each power spare oil duct is provided with switch respectively on the Hydraulic Pump; The axle of HM Hydraulic Motor is connected with the axle of four wheels in front and back respectively.

Engine output shaft is connected to a constant speed change speed gear box, and the speed change value is advisable about 1: 20, because like this, the rotating speed of power spare is lower.Output shaft after the change speed gear box speed change leads to the oil pressure pump of being made up of two synchronous sealing wheel dynaflow part groups (hereinafter to be referred as pump), pump is made up of three the coaxial series connected two wheel of sealing synchronously dynaflow parts, their inside oil pocket volume ratio is 1: 2: 4, oil circuit by three power spares of difference switch, carrying out that permutation and combination can obtain 1,2,3,4,5,6, the array mode of 7 seven kind of equivalent incremental flow value, just is that axle rotates a circle and can obtain seven different flow values equally.For the two wheel of sealing synchronously dynaflow parts (hereinafter to be referred as HM Hydraulic Motor) of a constant volume that is transferred to, just can produce seven different rotating speeds so.By moving the purpose that switch just can reach gear shift, novel part of the present utility model just.Oil pipe is connected on the axle head HM Hydraulic Motor that trailing wheel, front-wheel or trailing wheel add front-wheel, oil pipe is not have the such restriction of axle, can bending be arranged in the chassis (centre portion can be made up of steel pipe), utilize the conduction propelling vehicle motion of hydraulic oil pressure.Front and back wheel can easily convert forerunner, rear-guard and 4 wheel driven to all respectively by fluid motor-driven.And solved the problem of differential, and the off-side wheel path is far away during automobile turning, and just the flow of outside HM Hydraulic Motor is greater than the inboard, the trend that the just in time oriented meiobar of liquid flows, so, the disagreeable differential problem of orthodox car do not had at all.Three pumps can also can be controlled by the oil circuit switch by clutch control, more can the clutch again of first switch oil circuit.Because, even close the oil circuit of a pump, inner rotator is still rotated, long-time rotation can reduce mechanical efficiency, so, want clutch to open for long-time no pump, but reality is, the middle speed period of service is not long, all in the top-gear position, has not just had the trouble of clutch when starting for a long time yet.By the linear interception of the rotating plate in the oil main line, can allow the rotor of HM Hydraulic Motor be subjected to very big resistance, make the rotation of wheel be obstructed and slow down, like this, play the function of brake by the oil duct sectional area of control working connection.Seven grades should be distributed like this, and one grade is half grade of tradition shelves speed, and second gear is a grade of tradition grade speed, and six grades is five grades of tradition shelves speed, and seven grades is more fashionable now six grades.Can start to walk, move backward or climb for half grade, than having superiority of one grade of tradition.This is the syntagmatic of being bestowed by heaven.

Beneficial effect: traditional mechanical conductive mode has been changed into the liquid conductive mode, simplified the complicated structure of change speed gear box, cancelled vertical axletree, diff even brake facing, can compress a lot of costs, alleviated car weight simultaneously, the space in the headstock obtains liberation.

The specific embodiment

Driving engine 1 output shaft at first is connected to one to be decided than change speed gear box 2, utilize the two wheel of sealing synchronously dynaflow parts to be composed in series Hydraulic Pump 3 for base components, on each power spare oil circuit switch is set on the Hydraulic Pump, fixed output shaft than change speed gear box is connected with the axle of Hydraulic Pump, Hydraulic Pump is connected with HM Hydraulic Motor with oil duct 5 by oil duct 4, HM Hydraulic Motor is respectively the HM Hydraulic Motor 6 that drives traditional rear axle, the HM Hydraulic Motor 7 of individual drive trailing wheel and the HM Hydraulic Motor 8 of individual drive front-wheel, brake oil duct control piece 10 is set on the oil duct, utilizes highly pressurised liquid to constitute new automobile driving system for propulsion source.

Different driving engines will be distinguished type selecting and adjustment, and the working accuracy of hydrodynamic spare is the key of problem, and the switch of pump can be used electronically controlled mode, and button is arranged on the bearing circle, has cancelled traditional gear shifting handle; Two drive with the switching of 4 wheel driven become simple, cancel vertical axletree, diff even brake facing, key is to have cancelled change speed gear box, can save the cost of bulk, has alleviated car weight simultaneously, the space in the headstock obtains liberation.
