US12723833 - Self-propelled gun system
The patent describes a self-propelled gun system featuring a chassis with a recoil mitigation system that controls the distance between the chassis and the support surface during firing. It includes a brake control device that applies braking force to the wheel after the gun fires, allowing for gradual or intermittent braking in response to recoil.
Claim 1
1 . A self-propelled gun system, comprising: a chassis extending along an x-axis, a first end of the chassis and a second end of the chassis spaced apart from one another along the x-axis, the chassis extending along a y-axis, a first side of the chassis and a second side of the chassis spaced apart from one another along the y-axis, the x-axis being at right angles to the y-axis; a gun barrel having a barrel axis, the barrel being mounted to the chassis by a pivot mount, the barrel being pivotable relative to the x-axis about a pivot axis aligned and/or parallel with the y-axis; a chassis suspension system comprising a wheel arm extending away from the chassis to a wheel, the wheel being rotatably mounted on the wheel arm, the wheel configured for engagement with a support surface, the wheel arm and wheel configured to support the chassis a distance (Dz) apart from the support surface in a z-axis, the z-axis being perpendicular to the x-axis and y-axis; a recoil mitigation system operable such that a maximum recoil damping distance (Dz_max) of the chassis from the support surface in the z-axis is variable to thereby vary the available damping distance in the z-axis to absorb recoil force (Fr) from the firing of a projectile from the gun barrel; and a brake control device configured for applying a braking force to the wheel in response to movement of the chassis in the x-axis by a recoil force (Fr) from the firing of a projectile from the gun barrel, wherein the brake control device is configured for applying the braking force to the wheel after the firing of a projectile from the gun barrel and after the wheel has started rotating along the support surface in response to the firing of a projectile from the gun barrel, and wherein the brake control device is configured to gradually and/or intermittently apply the braking force to the wheel after the wheel has started rotating. a chassis extending along an x-axis, a first end of the chassis and a second end of the chassis spaced apart from one another along the x-axis, the chassis extending along a y-axis, a first side of the chassis and a second side of the chassis spaced apart from one another along the y-axis, the x-axis being at right angles to the y-axis; a gun barrel having a barrel axis, the barrel being mounted to the chassis by a pivot mount, the barrel being pivotable relative to the x-axis about a pivot axis aligned and/or parallel with the y-axis; a chassis suspension system comprising a wheel arm extending away from the chassis to a wheel, the wheel being rotatably mounted on the wheel arm, the wheel configured for engagement with a support surface, the wheel arm and wheel configured to support the chassis a distance (Dz) apart from the support surface in a z-axis, the z-axis being perpendicular to the x-axis and y-axis; a recoil mitigation system operable such that a maximum recoil damping distance (Dz_max) of the chassis from the support surface in the z-axis is variable to thereby vary the available damping distance in the z-axis to absorb recoil force (Fr) from the firing of a projectile from the gun barrel; and a brake control device configured for applying a braking force to the wheel in response to movement of the chassis in the x-axis by a recoil force (Fr) from the firing of a projectile from the gun barrel, wherein the brake control device is configured for applying the braking force to the wheel after the firing of a projectile from the gun barrel and after the wheel has started rotating along the support surface in response to the firing of a projectile from the gun barrel, and wherein the brake control device is configured to gradually and/or intermittently apply the braking force to the wheel after the wheel has started rotating.
