The technical scheme of the utility model is realized like this:

the utility model provides a measure device that pulls car as a house downforce and mass distribution which characterized in that: the automatic weighing device comprises a sleeve, an ejector rod, a weighing part and a transmission part, wherein a lower base is installed below the sleeve, the weighing part is installed on the sleeve, the sleeve moves along the vertical direction through the transmission part, the transmission part comprises a first gear and a transmission handle, the lower base is provided with a hollow channel, a screw rod and a screw rod nut are installed in the channel, the screw rod nut is fixed in the channel of the lower base, a tooth surface part matched with the first gear in a meshed mode is machined at the end part of the screw rod, and a second gear is driven to rotate through the first gear so as to achieve the effect that the screw rod moves relative to the lower base.

Preferably, the weighing part adopts elastic component and ejector pin, installs the elastic component on the ejector pin, and elastic component one end is installed on the ejector pin and the other end is installed in the sleeve, is carved with the scale on the ejector pin.

Preferably, the weighing part adopts an electronic sensor.

Preferably, the first gear is a basin angle gear.

Preferably, the tooth flank members comprise a second gear.

Preferably, the tooth surface component comprises a rack.

In summary, by accurately measuring the weight of the trailer tongue (the downward pressure of the trailer connector) and measuring the downward pressures of the four corners of the trailer, whether the front, back, left and right balance weights of the trailer are reasonable or not and whether the balance weights are within a safe value range or not can be judged, and the swing of the trailer in the advancing process can be effectively reduced, so that the traffic accidents caused by the swing of the trailer can be reduced.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.

Fig. 1 is a schematic view of an apparatus for measuring the mass distribution of a pressure cell in a trailer.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

As shown in fig. 1, the device for measuring the pushing force and the mass distribution of a trailer according to the embodiment can accurately measure the weight of a trailer tongue (the pushing force of a trailer connector), and comprises a sleeve 1, a push rod 9, a weighing piece and a transmission piece, wherein a lower base 2 is installed below the sleeve 1, the weighing piece is installed on the sleeve, the sleeve moves along the vertical direction through the transmission piece, the transmission piece comprises a first gear and a transmission handle 10, the lower base is provided with a hollow channel, a screw rod 3 and a screw rod nut 4 are installed in the channel, the screw rod nut 4 is fixed in the channel of the lower base, a tooth surface piece which is meshed with the first gear is machined at the end part of the screw rod, and a second gear is driven to rotate through the transmission of the first gear, so that the screw rod moves relative to the lower base.

The adoption second gear of tooth face spare, the lead screw tip install second gear 5, second gear 5 and first gear 6 mesh connection mutually, first gear 6 is installed at the sleeve inner wall through the axle, drives second gear 5 through the transmission of first gear 6 and rotates, preferably, first gear adopts basin horn gear.

So as to realize the movement of the screw rod relative to the lower base.

Aiming at the weighing piece, two structures are adopted: the weighing part adopts an elastic part 8 and an ejector rod 9, the elastic part 8 is installed on the ejector rod 9, one end of the elastic part 8 is installed on the ejector rod, the other end of the elastic part is installed in the sleeve, scales 11 are carved on the ejector rod, and the position of the scales at each corner is determined during use, so that the weighing device is very convenient.
