Embodiment Construction

[0026] will combine Figure 1 to Figure 7 Describe trailer coupler 1. The trailer coupler 1 is adapted to be mounted at the rear end of a towing vehicle such as a truck or trailer, and to engage with a connecting portion 100 of a tow bar 101 mounted on a trailer to be towed by the tow vehicle (the towing vehicle and the towed vehicle trailer not shown). In the illustrated example, the connection portion 100 is a hanging loop, and therefore, the connecting portion 100 will be referred to as a hanging loop hereinafter.

[0027] The trailer coupler 1 has a height H, a width W and a length L. When the trailer coupler 1 is mounted on a truck, the trailer coupler 1 is oriented such that the height H is vertical and the width W and length L are horizontal. The values ​​of H, L and W depend on application specific requirements, such as the size of the hitch ring 100 for which the trailer coupler 1 is intended.

[0028] The trailer coupler 1 comprises a guide funnel 2 which may alt...

Abstract

There is disclosed a trailer coupling (1) for connecting a trailer to a towing vehicle. The trailer coupling (1) comprises: a wearable support member arranged to abut against a connection portion (100) of a drawbar (101) mounted to the trailer, when the connection portion (100) is received by the trailer coupling (1) and positioned in a towing position; a movable coupling member having a first position such that the connection portion (100) can move into and out of the towing position, and a second position for securing the connection portion (100) in the towing position, the second position being such that the connection portion (100), when entering and leaving the towing position, pushes the coupling member to perform a movement; and a magnitude sensor (11) configured to provide a measure indicative of a magnitude of the movement and, thereby, capable of detecting that an amount of wear of the support member exceeds a predetermined threshold.

Description

technical field [0001] The invention relates to a trailer coupler for connecting a trailer to a towing vehicle on which the trailer coupler is mounted. Background technique [0002] Heavy vehicles such as trucks are often equipped with couplers that allow a trailer to be attached to the vehicle. An example of such a coupler is the "VBG 795V-2" sold by VBG AB, which coupler has a guide funnel for receiving the hitch of a towbar secured to a trailer, and a guide funnel for fastening the hitch. Vertically movable pin into the guide funnel. To connect the trailer to the truck, the pin is first manually lifted by the handle to the upper locking position, where the lower part of the pin still extends into the guide funnel. The truck driver then steers the truck to position the hanger within the guide funnel. After entering the guide funnel, the shackle contacts the lower part of the pin and thereby pushes the pin slightly upwards. Upward movement of the pin that releases the l...
