Abstract
The utility model relates to a transmission case of a load trailer, which comprises a shell, and a driving gear, a rear axle shaft, an output shaft, an intermediate shaft and a lubricating oil pump which are arranged in the shell, and also comprises an output gear, a transmission shaft and a transmission gear, wherein a sliding gear sleeve and the transmission shaft are additionally arranged in a case body; the transmission gear is arranged on the transmission shaft; a duplicate gear is additionally arranged on a rear axle output shaft; the sliding gear sleeve is meshed with the transmission gear and the driving gear on the transmission shaft so as to drive the rear axle output shaft to rotate; and the sliding gear sleeve is meshed with the duplicate gear, the rear axle output shaft is synchronized with the duplicate gear, and the intermediate shaft and the output shaft rotates so as to drive the lubricating oil pump and a dynamometer to work. The transmission case of the load trailer, which is disclosed by the utility model, has a simple and compact structure, and is easy to manufacture and convenient to operate; according to work orders of the dynamometer, the sliding gear sleeve is separated from or meshed with the duplicate gear through operating a gear shifting system, so the working or the outage of the intermediate shaft, the output shaft and the lubricating oil pump is controlled; and further, the maintenance cost of the transmission case is reduced, and the service life and the reliability of the transmission case are increased.
Description
Technical field
The utility model relates to a kind of gear drive, is specifically related to a kind of trailer transmission case that is used to load.
Background technique
Along with constantly development such as heavy vehicle and engineering machinery vehicle, for guaranteeing the Security and the reliability of vehicle, need measure the performance parameter of vehicle, the load trailer is exactly to be used for the vehicle testing equipment of testing vehicle dynamic traction performance, has obtained extensive use.Existing load trailer mainly is made of back axle, transmission case, connection set, speed change gear, power-measuring system.The shortcoming of the transmission case of this load trailer is that driving gear is more, the chassis structure complexity of feasible load trailer, and Heavy Weight, bearing capacity is limited; When not needing to test, power-measuring system is not worked, but a plurality of driving gears relevant with power-measuring system are turning round therefore this load trailer transmission case weak point in working life, maintenance cost height always.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provide a kind of trailer of both can having realized loading as common trailers, to walk, can the vehicles dynamic performance parameter be fed back to power measurer by certain speed ratio again, compactness simple for structure, long service life, the load trailer transmission case that maintenance cost is low.
Load trailer transmission case of the present utility model comprises housing and is arranged on housing interior driving gear, rear axle beam, output shaft, jack shaft and lubricating pump, it is characterized in that: have additional the duplex tooth on the described rear axle beam, have additional sliding gear collar on the driving gear; Sliding gear collar and the engagement of duplex tooth, the duplex tooth drives center tooth, output gear, jack shaft and output shaft, lubricating pump, output shaft and power measurer work successively.
Load trailer transmission case of the present utility model is simple in structure, easy to manufacture, easy to operate, instruct according to power measurer, by the operation shifting system sliding gear collar and duplex tooth being meshed controls jack shaft, output shaft and lubricating pump running, finishes the test of vehicle performance parameter; When power measurer was not worked, sliding gear collar separated with the duplex tooth, and jack shaft, output shaft and lubricating pump do not rotate yet, and have reduced the maintenance cost of transmission case, have improved its long service life and reliability.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, sliding gear collar, 2, the duplex tooth, 3, back axle, 4, jack shaft, 5, lubricating pump, 6, output gear, 7, power measurer, 8, shifting system, 9, rear axle beam, 10, driving gear, 11, center tooth, 12, output shaft, 13, housing.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
Load trailer transmission case of the present utility model has additional duplex tooth 2 by housing 13 and the driving gear 10, rear axle beam 9, output shaft 12, jack shaft 4 and the lubricating pump 5 that are arranged in the housing 13 on the rear axle beam 9, have additional sliding gear collar 1 on the driving gear 10.
Load trailer transmission case of the present utility model is work like this:
When needs are tested, by operation shifting system 8, make sliding gear collar 1 and 2 engagements of duplex tooth, duplex tooth 2 drives center tooth 11 successively and output gear 6 rotates, the running of jack shaft 4 and output shaft 12, power measurer and 5 work of built-in lubricating pump, by output shaft 12, power measurer 7 is finished tested vehicle performance parameter testing.
When not needing to test, by operation shifting system 8, sliding gear collar 1 is separated with duplex tooth 2, jack shaft 4 and output shaft 12 do not rotate, and power measurer 7 and built-in lubricating pump 5 quit work, and the load trailer is as the walking certainly of common car.
