Description

Motor installation and position adjustment base of transmission test system

Technical Field

The utility model relates to a detection device's motor mount pad, concretely relates to derailleur test system's motor installation and position control base.

Background

The gearbox is a key component in a vehicle transmission system, and the performance of the gearbox directly influences the economical and dynamic performances of the automobile. And the performance data of the gearbox is accurately measured, and the basis for ensuring the continuous optimization design of the gearbox in the development process is also provided. Therefore, in the development of gearboxes, gearbox bench tests for performing various types of performance tests are indispensable.

At present, the hybrid power technology is concerned by the advantages of low noise, good power performance, high specific energy and the like. The traditional power assembly of the internal combustion engine consists of a hole drilling machine and a traditional gearbox, and the power assembly of the compound power locomotive consists of an engine, a driving motor generator and a hybrid power gearbox. Because the positions of the input shafts corresponding to the hybrid power gearbox are different according to different working conditions, the horizontal position and the longitudinal installation height of the engine installation seat corresponding to the hybrid power gearbox are required to be adjusted when the engine installation seat is used for testing different working conditions, so that the coaxiality of the input shafts of the engine and the hybrid power gearbox is ensured. The existing motor mounting seat is a fixed seat with a mounting platform at the upper end, the position and the height of the existing motor mounting seat can not be adjusted according to different working conditions during measurement, and the horizontal position can only be moved by pushing the mounting seat, so that time and labor are wasted.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a motor installation and position adjustment base of a transmission testing system comprises a base with a supporting plane at the upper end and a testing motor fixed on the base, and is characterized in that a rectangular cushion block is detachably installed on the supporting plane of the base, and the lower end face of the testing motor is detachably installed on the cushion block; the lower end of the base is also provided with a bottom plate, one end of the bottom plate is arranged in the base and is connected with the bottom, the other end of the bottom plate extends out of the base, the bottom plate can be driven to slide on the bottom plate under the action of external force and can be positioned, and the sliding direction of the base is perpendicular to the output shaft of the test motor. Therefore, the cushion block with the proper height can be selected according to the installation height of the input shaft of the hybrid transmission to be tested by the cushion block arranged on the base, so that different assembly heights of the test motor can be adapted. And the base plate and the displacement mechanism arranged below the base can facilitate the base to move in a horizontal direction, and ensure that the output shaft of the test motor is coaxial with the other input shaft of the hybrid transmission after the base moves. Because the test motor assembles on the cushion of base, consequently, as long as horizontal migration base, can change the horizontal position of the output shaft of test motor, and after changing the not co-altitude cushion, can make the test motor adapt to the not co-altitude of test motor output shaft to satisfy the test needs.

Furthermore, a half shaft perforation which is parallel to the axial lead of the motor output shaft and is used for penetrating through the test half shaft is arranged on the cushion block. Therefore, the half shaft through hole can be used for penetrating the half shaft, and the test bench can simulate the assembly environment of the hybrid gearbox and the half shaft in the precursor system conveniently.

Furthermore, the displacement mechanism is a worm gear and worm linear transmission mechanism and comprises a rotating handle, the lower end of the rotating handle is connected with a worm, the worm is vertically arranged, one side of the worm is provided with a worm gear meshed with the worm, the worm gear is fixed on a screw rod, and the screw rod is positioned above the bottom plate and is vertical to an output shaft of the test motor; an internal thread sleeve which is in threaded fit with the screw rod is arranged in the base, and the inner end of the screw rod is arranged in the internal thread sleeve and is in threaded fit with the internal thread sleeve. Therefore, the worm and gear linear transmission mechanism is used as a displacement mechanism, when the base needs to be horizontally displaced, only the rotating handle needs to be rotated, and the rotating handle drives the worm to synchronously rotate after being rotated and drives the worm gear meshed with the worm to rotate. After the turbine rotates, the screw rod connected with the turbine can synchronously rotate, and the base is in threaded connection with the screw rod, so that after the screw rod rotates, the base can horizontally displace and position under the action of threads.

Furthermore, a vertical plate for supporting the screw rod is arranged on the bottom plate. Therefore, the vertical plate can facilitate the assembly of the screw rod and support the worm gear mechanism.

Furthermore, two guide through grooves parallel to the screw rod are arranged on the bottom plate at intervals, and each guide through groove is a T-shaped groove with a wide lower end and a narrow upper end; and the bottom of the base and four corners of the base are respectively provided with a sliding block corresponding to the guide through groove. Therefore, when the base moves, the sliding blocks slide in the two guide through grooves, so that the base can be stably moved, and the offset phenomenon cannot occur. And after the guide through groove is of a T-shaped structure, the sliding block can be prevented from falling off from the guide through groove.

Furthermore, the upper end of each sliding block is detachably connected with a screw, four operation openings which are in one-to-one correspondence with the sliding blocks are formed in the lower end of the base, and the screws are arranged in the operation openings and penetrate through the base to be connected with the tops of the sliding blocks. Like this, the slider passes through the screw rod to be fixed on the base, and is firm with base connection structure, and simultaneously, the operation mouth that sets up is convenient for the screw rod to be connected with the slider top from operation mouth department, and the operation mouth can be convenient for the installation and the dismantlement of screw rod.

Furthermore, the upper end of the base and the two opposite sides of the base are at least provided with one mounting groove, and a fastening bolt with the tail end connected with the cushion block is arranged in each mounting groove. Like this, through fastening bolt fixed connection between base and the cushion, the mounting means is simple, and connection structure is firm. And the installation groove can facilitate the rotation operation of the fastening bolt.
