Description
Technical field
The invention belongs to vehicle test device technical field, be specifically related to a kind of gearshift of cable type wheel box testing table.
Background technology
On some cars, medium-and-large-sized passenger vehicle and lorry, distant due to overall layout requirements position of driver and wheel box, the normal flexible shaft manipulation mechanism that adopts carries out remote gearbox shifting manipulation, and structure is simple, and handle light, transmission efficiency is high.
Carry out wheel box test, when power assembly test or complete vehicle test, all need the gear constantly changing vehicle in process of the test.If by artificial gearshift, need to stop after the test completing a gear, the dynamic test process of gearshift continuously cannot be completed, therefore, need a kind of gearshift to replace manually to carry out self shifter.At present, the object that testing table gearshift controls is all the manipulation hand lever of gearshift assembly, and maneuverability pattern has multi link formula and slide block type etc.Sliding block type structure is simple, but is difficult to meet the different hand lever of size and dimension, and versatility is poor, and installs inconvenient; Multi link formula has broken away from the restriction of hand lever size and dimension, but complex structure, cost is high.For cable type wheel box, handle the motion of hand lever is converted into all flexible axles push-and-pull Movement transmit by being decomposed and be coupled to wheel box end, as long as therefore gearshift makes flexible axle produce identical push-and-pull campaign that wheel box just can be made to complete gearshift.Be integrated in gearshift by the manipulation hand lever of gearshift assembly, the object of control is flexible axle, and versatility is good, and structure is simple, only need be installed on gearshift by the flexible axle of wheel box during installation, very convenient.
The flexible shaft manipulation mechanism of cable type wheel box is different, the quantity of flexible axle and mode of motion difference to some extent.The version of the flexible shaft manipulation mechanism of flexible axle wheel box mainly contains two kinds, and one is block selecting, gearshift split, and namely the push-and-pull of block selecting flexible axle completes wheel box block selecting, and the push-and-pull of gearshift flexible axle completes gearbox shifting; Another kind is block selecting, gearshift synthesis type, and namely block selecting and the gearshift of wheel box has been synthesized in the push-and-pull of two flexible axles, and now flexible axle is regardless of block selecting and gearshift.Some cable type wheel boxes, except block selecting and gearshift two flexible axles, also have a flexible axle to be responsible for power-assisted.The diversity of flexible shaft manipulation mechanism is for being applied to cable type wheel box, and control object is that the structural design of the gearshift of flexible axle brings difficulty.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, propose a kind of gearshift of cable type wheel box testing table, the present invention can adapt to different flexible shaft manipulation mechanism, and structure is simple, operates steadily, easy for installation, highly versatile.

A gearshift for cable type wheel box testing table, comprises regulator cubicle, the electronic slide unit of block selecting, shifts gears with electronic slide unit, mechanical arm, slide block, rocking arm, universal joint, flexible axle and bearing; Block selecting electronic slide unit and the electronic slide unit of gearshift at right angles intersect installation up and down, the electronic slide unit of block selecting is laterally fixed on regulator cubicle top by screw, gearshift is vertically fixed on the nut seat of block selecting with electronic slide unit by screw with electronic slide unit, is fixed by screws on the nut seat of gearshift with electronic slide unit bottom mechanical arm; Side shaft and the mechanical arm front end of slide block are hinged; The top of rocking arm is connected with skid, and slide block can be slided on rocking arm; Universal joint top is fixed by screws in bottom rocking arm; Holder top is fixed by screws in bottom universal joint; In flexible axle, core head is fixed on rocking arm bottom panel, and flexible axle tube wall is fixed on bearing panel.
Described mechanical arm comprises large arm, bearing seat and minor axis; Two bearing seats are fixed by screws in large arm front end and form entry, and entry coordinates with minor axis built with bearing; Have circular hole in the middle of minor axis, circular hole, built with bearing, can match with slide block side shaft, and by double nut to top locking, is formed hinged; Rocking arm comprises sleeve and rocking bar, and sleeve bottom is internal thread hole, and rocking bar has external thread, and both are threaded connection; In slide block endoporus, linear ball bearing is housed, matches with sleeve, slide block can be slided on rocking arm; Described slide block can either rotate around minor axis center pit axis, can slide again along sleeve, thus enables rocking arm left and right and swing.
The four edges of described rocking arm bottom panel respectively has elongated slot, and the correspondence position of bearing panel also has elongated slot, right-angle connector surface level has two holes, is fixed by screws in rocking arm bottom panel elongated slot; Right-angle connector vertical plane has a through hole, and in flexible axle, core head is fixedly connected with right-angle connector vertical plane through hole by bolt, and flexible axle tube wall is bolted in the elongated slot being fixed on bearing panel.
The beneficial effect that the present invention will reach is:
The present invention is applied in cable type wheel box test-bed, can realize the self shifter of wheel box.The present invention simultaneously has good versatility, can adapt to the wheel box of varying number, different flexible shaft manipulation mechanism.Further, structure of the present invention is simple, installs very convenient, only all flexible axles of wheel box need be fixed to the correspondence position of gearshift.In addition, shift process, by driven by servomotor, operates steadily, and positioning precision is high, and speed and the stroke of its gearshift all can set in a program, and controllability is good.
