Separable tow hook brake release system

An electric mining vehicle, comprising

• a removable battery frame, the removable battery frame including:
• a tow hook,
• a tow hook cylinder, and
• a transfer cylinder, the transfer cylinder being hydraulically connected to the tow hook cylinder;
• the transfer cylinder being located on a front side of the removable battery frame, and the tow hook and tow hook cylinder both being located on a rear side of the removable battery frame, opposite the front side of the removable battery frame;
• and
• a main body portion of the electric mining vehicle;
• wherein:
• the removable battery frame reversibly attaches to a rear area of the main body portion;
• the main body portion of the electric mining vehicle includes a receiver cylinder hydraulically connected to a brake release mechanism, the receiver cylinder being located on the rear area of the main body portion;
• the tow hook cylinder is located on the removable battery frame such that the tow hook cylinder is mechanically actuated when a towing vehicle attaches to the tow hook;
• the tow hook cylinder is configured to hydraulically actuate the transfer cylinder when the tow hook cylinder is actuated;
• the receiver cylinder on the main body portion is aligned with the transfer cylinder on the removable battery frame, such that the transfer cylinder is configured to mechanically actuate the receiver cylinder when the transfer cylinder is actuated;
• and
• the receiver cylinder is configured to hydraulically actuate the brake release mechanism when the receiver cylinder is actuated.

A vehicle, comprising:

• a detachable portion including a tow hook and a first hydraulic system;
• a main body portion including a brake release mechanism and a second hydraulic system connected to the brake release mechanism;
• wherein the detachable portion is separable from the main body portion of the vehicle by mechanically disengaging a mounting and dismounting system;
• wherein the first hydraulic system and the second hydraulic system are mechanically connected to each other;
• and
• wherein actuation of the first hydraulic system mechanically causes actuation of the second hydraulic system, and actuation of the second hydraulic system causes a break release mechanism to release brakes on the vehicle;
• and
• wherein the vehicle is an electric mining vehicle.

A vehicle, comprising:

• a main body portion including a brake release mechanism and a second hydraulic system connected to the brake release mechanism;
• wherein the detachable portion is separable from the main body portion of the vehicle by mechanically disengaging a mounting and dismounting system;
• wherein the first hydraulic system and the second hydraulic system are mechanically connected to each other;
• and
• wherein actuation of the first hydraulic system mechanically causes actuation of the second hydraulic system, and actuation of the second hydraulic system causes a break release mechanism to release brakes on the vehicle;
• and
• wherein the first hydraulic system includes a tow hook cylinder located on a lower portion of a rear side of the detachable portion, the tow hook cylinder being configured such that it is mechanically actuated when a towing vehicle connects to the tow hook.

• and
• wherein actuation of the first hydraulic system mechanically causes actuation of the second hydraulic system, and actuation of the second hydraulic system causes a break release mechanism to release brakes on the vehicle;
• and
• the first hydraulic system includes a tow hook cylinder and a transfer cylinder, the tow hook cylinder and the transfer cylinder being hydraulically connected to each other;
• the second hydraulic system includes a release actuator, the release actuator being hydraulically connected to the brake release mechanism;
• the transfer cylinder includes a first alignment structure;
• the release actuator includes a second alignment structure;
• and
• the first alignment structure and the second alignment structure physically interface with each other, such that a transfer force is applied by the transfer cylinder to the release actuator.
