Abstract
The utility model discloses a rolling wheel device of a vehicle testing saddle piece, which comprises a central shaft and a rolling wheel which can rotate around the central shaft. The utility model is characterized in that a positioning pin for limiting the rolling wheel to rotate is arranged on the rolling wheel, the positioning pin is moveably connected with the central shaft, and both ends of the central shaft are connected with supporting bar whose lengths can be adjusted. Screw threads are arranged on the supporting bar, whose length can be adjusted and female screws are screwed on the supporting bar, and the female screw supports the central shaft. And a locking female screw is also arranged on the supporting bar. And the rolling wheel device can be formed by two sections of bars which are mutually sleeved through screw threads. Since the positioning pin which can limit the rolling wheel to rotate and is arranged on the rolling wheel is adopted, the positioning pin is moveably connected with the central shaft, and both ends of the central shafts are connected with supporting bars whose lengths can be adjusted. The rolling wheel device is freely combined into rolling rows with different lining forms, and the vehicle testing saddle piece can simulate various road conditions to do all-round testing for the performance of vehicles, and the rolling wheel device is convenient to employ, whose cost is little, and which is a simple and practical rolling wheel device of vehicle testing saddle pieces.
Description
Technical field
The utility model relates to a kind of roller devices, especially relates to a kind of roller devices of vehicle test stand.
Background technology
At present, domestic each big producer is all competitively producing SUV and offroad vehicle, but especially the test method and the test-bed of offroad vehicle performance is considerably less to weigh vehicle, and it is more and more difficult to look for typical bad road surface to test, a lot of for this reason main engine plants do experiment at some sandy beaches, Gobi desert of making light of travelling from afar, the appropriate litigation fees height, and after having gone bad, because of meagrely-populated, maintenance is difficulty quite.Chinese patent discloses a kind of car test bench No. 87206586, and main rigid plane by car body fulcrum arrangement, four energy rotations substitutes road surface and torque compensation motor and substitutes the road surface rotating mechanism to be formed.In order to improve measuring accuracy, substituting the road surface adopts the both sides that are fixed on the chain to have the rest pad structure of shaggy tooth, snubber assembly is housed on rest pad, has also adopted the thrust wheel that has groove, the flexible oil groove of annular corrugated formula is housed between chain and rest pad.Its weak point is, the structure more complicated, and the rigid plane of four energy rotations substitutes the road surface and adjusts inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is, in order to remedy the weak point of roller devices in the existing vehicle test stand, and provides a kind of easy to adjust, and the roller devices of simple and practical vehicle test stand.
The utility model is to solve the problems of the technologies described above to adopt following technical scheme: the roller devices of vehicle test stand, the roller that comprises central shaft, rotates around central shaft, it is characterized in that: the register pin that the restriction roller rotates is set, the movable central shaft that connects of register pin on roller; The support bar that connects variable-length at the central shaft two ends.
The support bar of described variable-length is screw thread to be set on support bar and to be rotary with nut, the nut support central shaft.Set nut also is set on support bar.
The support bar of described variable-length can also be made up of two sections bars of mutual screw thread socket.
The roller devices of described one group of vehicle test stand can freely form different spread pattern rolling rows, simulates different road conditions, and the performance of vehicle is done various tests.
The utility model good effect is owing to adopt the register pin that the restriction roller rotates to be set on roller, the movable central shaft that connects of register pin; The support bar that connects variable-length at the central shaft two ends.The vehicle test stand just can be simulated various road conditions, and the cross-country ability of vehicle is done comprehensive check, and it implements convenient, and expense is few.It is a kind of roller devices of simple and practical vehicle test stand.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Description of drawings
Fig. 1 is the roller devices organigram of vehicle test stand.
Among the figure: 1. roller, 2. central shaft, 3. support bar, 4. nut, 5. register pin.
Embodiment
The support bar of embodiment 2 described variable-lengths is made up of two sections bars of mutual screw thread socket.All the other are identical with embodiment 1.
The roller devices of 3 one groups of vehicle test stands of embodiment, the rolling that can freely form different spread patterns is arranged, and simulates different road conditions, and the performance of vehicle is done various tests.As constituting a vehicle test stand by 4 rows of rolling, the height of the roller devices in each row of rolling can be adjusted by the support bar of variable-length, and they can be adjusted into different arrangement modes according to different test events.Each roller devices can freely rotate also can fix locked.In these 4 rows of rolling, the distance of front and rear row is slightly less than the wheel base of vehicle, about row centre distance be the left and right vehicle wheel wheelspan, each row's width is greater than the width of tire, it is fixed that its concrete size will be come according to the vehicle of test, but same type wheel can be designed to identical size, to guarantee the versatility of experimental stand maximum apart from being more or less the same.
On this test-bed, when we do the test of four-wheel drive vehicle trafficability characteristic, be divided into three kinds of situations: 1, two front-wheels or the two trailing wheels situation of getting down hopeless in a quagmire, 2, two left side tires are got down hopeless in a quagmire or two situations that the right side tire is got down hopeless in a quagmire, and 3, the near front wheel and off hind wheel or off-front wheel and the left rear wheel situation of getting down hopeless in a quagmire.If roller is arranged in echelon, can also be tested the ability of its across obstacle.Poor by constantly strengthening the adjacent rollers height of devices, can be with the maximum height of the across obstacle that tests out it.Can also simulate various situations such as concavo-convex road surface by the arrangement mode of adjusting roller devices in addition.
Claims (4)
1. the roller devices of a vehicle test stand comprises central shaft, around the roller that central shaft rotates, and it is characterized in that: the register pin that the restriction roller rotates is set, the movable central shaft that connects of register pin on roller; The support bar that connects variable-length at the central shaft two ends.
2. roller devices according to claim 1 is characterized in that: the support bar of described variable-length is screw thread to be set on support bar and to be rotary with nut, the nut support central shaft.
3. roller devices according to claim 2 is characterized in that: set nut also is set on support bar.
4. roller devices according to claim 1 is characterized in that: the support bar of described variable-length, form by two sections bars of mutual screw thread socket.
