Description

Technical Field

[0001] This utility model relates to the technical field of vehicle torque comprehensive test benches, and in particular to a vehicle torque comprehensive test bench. Background Technology

[0002] Vehicle torque refers to the torque output from the crankshaft of the engine, reflecting the force that the engine can output when running. The greater the torque, the better the vehicle's acceleration performance and the more load it can pull. With a fixed power, torque is inversely proportional to engine speed; the faster the speed, the smaller the torque, and vice versa.

[0003] After a vehicle engine is manufactured, it is generally placed on a test bench to test whether its torque meets expectations. During the production process, round holes are usually pre-drilled to secure the engine to the vehicle using bolts. However, the spacing between these round holes varies for different engine specifications. This necessitates that the test bench be compatible with multiple engine specifications to facilitate torque testing of various engine sizes. Therefore, a comprehensive torque test bench for vehicles is proposed. Utility Model Content

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1-8 As shown, this utility model embodiment provides a vehicle torque comprehensive test bench, including: a base 1, on which an electric push rod 2, a first power assembly 3, and a second power assembly 4 are fixedly installed. The first power assembly 3 is threadedly fitted with two first sliding seats 5, and the second power assembly 4 is threadedly fitted with a sliding assembly 6. The sliding assembly 6 is slidably fitted with two second sliding seats 7. Bolts 8 are threadedly fitted into the two first sliding seats 5 and the two second sliding seats 7. A sliding plate 9 is fixedly installed on the output end of the electric push rod 2. A torque testing assembly 10 and a loading assembly 11 are fixedly installed on the sliding plate 9. The torque testing assembly 10 and the loading assembly 11 are fixedly connected. Four third guide rods 25 penetrating the base 1 are fixedly installed on the sliding plate 9.

[0029] In this embodiment, specifically: the first power assembly 3 includes a first motor 12 fixedly installed on the base 1 and a first threaded rod 13 fixedly installed on the output end of the first motor 12. The installation of the base 1 facilitates the installation of the electric push rod 2.

[0030] In this embodiment, specifically: the two ends of the first threaded rod 13 are threadedly engaged with the two first sliding seats 5, and two first guide rods 14 for guiding the two first sliding seats 5 are fixedly installed on the base 1. The installation of the first threaded rod 13 facilitates the sliding of the first sliding seats 5.

[0031] In this embodiment, specifically: the second power assembly 4 includes a second motor 15 fixedly installed on the base 1 and a second threaded rod 16 fixedly installed on the output end of the second motor 15; the sliding assembly 6 includes a sliding strip 17 threadedly engaged with the second threaded rod 16 and a guide strip 18 fixedly installed on the sliding strip 17; the installation of the second threaded rod 16 facilitates the sliding of the two second sliding seats 7.

[0032] In this embodiment, specifically: two second guide rods 19 for guiding the sliding bar 17 are fixedly installed on the base 1, and two second sliding seats 7 are slidably engaged with the guide bar 18. The installation of the sliding bar 17 facilitates the sliding of the guide bar 18.

[0033] In this embodiment, specifically: the torque testing component 10 includes a dynamic torque sensor 20 fixedly mounted on the sliding plate 9 and a torque power meter 21 electrically connected to the dynamic torque sensor 20; the loading component 11 includes a loading motor 22 fixedly mounted on the sliding plate 9 and a speed regulator 23 electrically connected to the loading motor 22; a sliding tube 24 is slidably fitted at one end of the dynamic torque sensor 20; during the sliding process, the sliding tube 24 is not easily disengaged from the dynamic torque sensor 20, thereby allowing the dynamic torque sensor 20 to be connected to the engine; the dynamic torque sensor 20 and the output end of the loading motor 22 are fixedly connected by a coupling.

[0034] When this utility model is in operation: When the device needs to fix engines of different specifications, the four bolts 8 are rotated to disengage from the device, and then the engine is hoisted onto the device using a crane. At this time, the positions of the two first sliding seats 5 and the second sliding seats 7 are adjusted according to the round holes at the bottom of the engine for fixing the engine. The first motor 12 and the second motor 15 are turned on. The first motor 12 drives the first threaded rod 13 to rotate. At this time, the two first sliding seats 5 slide closer or further away from each other. The second motor 15 turns on and drives the second threaded rod 16 to rotate. At this time, the sliding strip 17, the guide strip 18, and the second sliding seats 7 slide. As the second sliding seats 7 slide away from or closer to the first sliding seats 5, the two second sliding seats 7 slide on the upper side of the guide strip 18, so that the freely sliding second sliding seats 7 can slide to the lower side of the engine's round hole. Then the engine is placed on the two first sliding seats 5 and the second sliding seats 7, and then the bolts 8 are used to fix the engine to the first sliding seats 5 and the second sliding seats 7.

[0035] Different models of engines have different heights at their output ends. After the engine is fixed, the electric push rod 2 is turned on. The turning on of the electric push rod 2 causes the sliding plate 9, torque test component 10, and loading component 11 to rise and fall. When the torque test component 10 is raised and lowered to the same axis as the engine output end, the sliding tube 24 is fixedly connected to the engine output end.

[0036] When engine torque needs to be tested, the engine is started, and then the loading motor 22 is turned on. After the engine starts, it rotates actively, and the output power is transmitted to the dynamic torque sensor 20 connected to it. The dynamic torque sensor 20 passively follows the rotation and detects the torque and speed output by the engine in real time. Then the power is transmitted to the loading motor 22. The loading motor 22 initially rotates passively, but when the speed controller 23 is activated, it supplies power to the loading motor 22 and controls the loading motor 22 to apply a reverse braking torque, thereby simulating real road resistance. The engine needs to overcome this resistance to continue rotating. The dynamic torque sensor 20 continuously records the real torque and power generated by the engine against the resistance throughout the process. Finally, the data is collected and displayed by the torque power meter 21 to form a complete test result. The speed controller 23 controls the operation of the loading motor 22, such as torque magnitude, speed, forward and reverse rotation, and braking. The loading motor 22 is used to simulate resistance or road load, receive external torque and brake in the reverse direction. The torque power meter 21 reads the dynamic torque sensor 20 and displays the power, speed, and torque. The dynamic torque sensor 20 is used to collect real-time torque and speed information.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
